Specification of Letters Patent.

LESAW.

To all whom t may concern.'

4Be it known that I, WILLIArr A. COL-v LINGs, a citizen of the United States, anda resident of Kansas City, in the county' of Jackson and State of Missouri, have invented certain newA and useful Improvements in Safety-Blade Knives; and yI do hereby declare that the following isy a full,

clear, and exactdescription of the same, reference being had vto the` accompanying drawings, and to the numerals of reference marked thereon, which-form a part of this specification.

There are many different kinds of safety razors in use, in which detachable double edged safety blades are used, of a type similar to the Gillette safety razor blades. These blades are, of course, adaptable for shaving purposes for a limited length of time only, after' which the blades aredisi carded as useless, resulting in the waste and destruction (if-material that might be reused to advantage.

This invention relates knife, consisting of few parts and adapted to receive detachably mounted therein used safety razor blades after the same'have served their purpose, and are no longer adaptedl for use in shaving, thusrnaking it possible to utilize the blades for cutting, paring and other purposes. I

lftis an object of this invention to construct a knife handle adapted to receive a safety razor blade mounted therein.

llt is also an object of this invention to construct a knife, to receive a safety razor blade for use therein, and which affords a shield or covering therefor when the knife f The invention (in a preferred form) isv illustrated in the drawings and hereinafter j more fully described.

lln the drawings: Figure l is a conventional side elevation to a safety bladey lmargin of said handle l, and said not purpose of a device embodying the principles of my invention shown in closed position.V

Fig. 2 is a section taken on line 2--2, of Fig. l.

\Fig. 3 is a horizontal section view taken through the device when in open position, showing parts in elevation.

Fig. 4 is a section taken on line 4.-4, of Fig. 3, showing the complete side view.. 1

As shown in the drawings:

The device consists of a handle 1, com posed preferably of metal, althoughpther material suitable for the purpose may be used; said handle 1, having inwardly stamped indents forming circular knobs or projections 2, formed near one end thereof,

,and as clearly sho-wn in Fig. 4, also provided said handle. Detachably mounted on said handle l, is an apertured Gillette or other safety razor blade 4, the apertures thereof engaging over said projections 2, to hold the blade secure. To positively retain said blade 4, in position and'prevent the same becoming disengaged from the indents 2, a plate 5, is slidably fitted within said flange 3, and frictionallyheld therein. One edge of said blade 4, projects above the upper plate 5, to

afford a cutting edge.l Pivotally mounted on Patented aan@ s, fait. Application filed September I0, 1915. Serial No. 49,969. i

said handle 1, by means of a rivet 6, or

other suitable means is a guard handle 7, of lll-section, having an integral hood or guard 8, also of U-section, formed thereon.

the same to close over said handle 1, to 1nclose and protect the blade 4, when not in use.l

The operation is as follows:

Theoperation of thel device is simple and with the knife open as shown in Fig. 4, the blade 4, may be removed and replaced by simply sliding the plate 5, out of engagement with the flange 3.

am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and l therefore do 'limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

l. lln a device ofthe class described, a

handle, a razor blade, intertting elements Said guard handle 7, and hood 8, are open ,Y at their ends and along one side, to permit fea guardplvotally mounted on the other end of said handle and adapted to Afold over and cover the same. l 2. ln a device of the class described,a

l handle, projections integrally formed thereon and adapted for engagement withl a safety razor blade, sides.. of said handle .for slidably receiving a plate, aflange on three said plate to hold said blade in ,-position,

and a cover guard pivotally 'mounted on the other end of `said handle and adapted -15 v to fold over andcover the same.

In testimony whereof I have hereunto subscribed Vby naine in the presence of two subscrlbing witnesses. A
